Not at all! If you don’t plan your itinerary, you’ll at least have very different experiences from those who just go to tourist attractions. You might really SEE Paris and not just visit Paris. By the way, I have a strange fascination for Hooker streets. Even my first time in Geylang was memorable. I always wonder what goes through their heads and imagine all their background stories when I walk past them. Cheap thrills! Haha :)
